HEATER FOR ENGINECOOLING SYSTEMS.

Specification of Letters Patent.

Patented Apr. 4, 1916.

i To all whom itmay concern;

Be it known that I, SAMUEL V.. 'WIGHT, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio,- have invented new and useful Improvements in Heaters for Engine-Cooling Systems, of which the following is a specification.

This'invention relates to heaters for en- 'gi'necooling systems, the object of the invention being to provide a. simple, economical and effective heating apparatus by means of which water contained in the circulatory cooling system of an internal combustion engine may be maintained at a suitable temperature to prevent freezing and to facilitate the starting ofthe engine, when said engine is out of use.

Automobiles, motor-trucks and other vehicles propelled by internal combustion en- ...gines are frequently, by necessity, left standing in exposed places in cold weather for a considerable period of time sutficient to enable the cooling water to freeze and seriously injure various parts of the engine and its equipment such as. the cylinders, pump and radiator, and the aim of this invention is to overcome such liability by means of a simple apparatus applicable to any automobile, motor truck or the like which will prevent the water from freezing, thereby avoiding injury to the parts referred to and I also keeping the engine, radiator and other '1 is a side elevation partly in section showingthe heatihg apparatus this invention 1n its relation to an automobile. Fig. 2 IS a I detail elevation of the h'eii'ter. Fig. 3 is a vertical diametrical seetron through the heater. Fig. dis a fragmentary Vertical section through the lower portion of the heater] One method of applying the heating apparatus of thisinvention is illustrated in Fig. '1 wherein 1 designates the radiator which is ordinarily located in front of the engine of the machine, :2 designating the frame of the'automobile, 3 the front springs and 4 one of the front steering wheels-of the machine.

The apparatuscontemplated in this invention comprises a lamp or heater 5 which as shown in Fig. 3 embodies an outer casing 6 and an inner shell 7 arranged in spaced but concentric relation to each other, the inner shell 7 being. surrounded by a covering of asbestosas shown at 8 to conserve the heat within the casing.

Connected to the bottom of the casing in any convenient manner is a fuel container or font 9 which supplies a'burner 10 shown as of the ordinary wick form, 11 designating the wick raiser. The burner also comprises a top embodying an outer wall 12 and an inner wall 13 in spaced relation to each other so as to permit the air to enter through opening 1% in the top of the casing. the air passing downwardly between the casing G and shell 7 and between the base 15 and a contracted bottom portion 16 of the inner shell 7 and thence upward to supply the necessary oxygen to the flame of the burner .10. The air heated by the burner passes upwardly through the heater and escapes through the outlet orifices 17 adjacent to the top of .the burner thus prcvcntingthe flame from being extinguished in windy weather.

Located within the central body portion" of the heater is a water hcating coil 18 pro t-' crably of frusto-couical shape as shown in Fig. 3 and forming a. continuation of an inlet pipe 19 and an outlet pipe 20.

The pipe 1.) may be made of any suitable length and is provided with a coupling 21 adapting'it to be attached to a suitable point in the water cooling system of the en gine such as the bottom of the radiator as indicated in Fig. 1. Said pipe 19 is provided adjacent to its extremity or, in other words. adjacent to the coupling 21. with a stop cook 22. The other pipe 20 is recurvcd as shown in Fig. 1 to extend down under the radiator. in the embodiment of the invention illustrated in Fig. 1 and thence upward where it is connected by a suitable coupling 23 to the top of the radiator and equipped adjacent to said point with a stop cook 24; The stop cocks 22 and Q'enable rod mull

' the heating system of this invention to be radiator or the pump or the 'just the same to the proper hel "the automobile or other freezing and fracture ta placed in communication with or cut oil from communication xvi a. the cooling sys tem of the engine.

Itis to be understood that the arrange ment shown inF-i 1 is only one embodi meut of the 'invention. [the pipe will ordinarily be connected to the lowest point in the circulatory cooling system the engine, such point to be at the bottom of the Water jackets of the cylinder. The idea i5 to take the Water fromthe lowest point of said circulatory' cooling system and carry it to the heater of this invention and from said heater return the water into the cooling system at a relatively bi h point. llhis insures r a thermo-sioh on action and insures the heat-- ing of all the Water in both the heating sys tem of this invention and the ordinary Water cooling; system oi the engine.

The heater is preferably prcWid-M.v at one side Vith an attaching lug 335 formed with a slot 26 to receive the usual su nsorting bracket attached to any convenient part of the machine frame as, for example, the frame 2 in Fig. 1. lit will however, be apparent that the heater may be supported on. any convenient part of the machine. I

'l' i hen the operator leaves his car for a long period in cool weather, it is only necessary to light the burner of the heatc and aid-- g in ac cordance with the temperature at the time. The heater gradually .Warnis the Water and induces a. circulation through thepipes 19 and 20 and consequently through the circulatory Water systcnr of the engine. This pie vents the water from freezing and also keeps the engine Warm and in condition for starting. Therefore, it is not necessary prime the engine in'orderto start the same, thus saving fuel. Furthermore, the owner of machine is relieved ofwo rry and is reliei 'ed of the expense'of repairing achineto a water contain- I I! l mg'parts or the engine auc. its equipment.

The cap or closure 28 may be hinged e drawings, it is impossible to ignite fumes of gasolene or the like a'ndturthermore the draft arrangement prei'ents mud. Water and other foreign matter from getting into and accumulating Within the heater so as to clog and interfere with the operation thereof, it being unnecessary to use any screen for the purpose. Furthermore, by reason of the particular construction of the lamp and the relative arrangement of the parts thereof, the inner and outer shells of the heater are thoroughly and effectively braced relatively to each other thereby greatly increasing the life and durability of the heater which is necessarily subjected to the almost continuous jars and vibrations of the machine upon which it is used. What I claim is:

A water heater for the purpose specified,

comprising an outer shell embodying a bylindrical central body portion and upper and lower frusto-conical end portions, ac'onico cylindrical inner.. she]l gradually 'contracting in diameter upward and then extended to form acylindrical closed top chimney which passes through and closes the top of the cute shell and formed with lateral outlet ports-above said outer*sl1el. l,- the latter being formed. with air inlet ports adto its 'j unction with the chimney, a frustoconical water coil all of the'ccnvolutions of which lie in close. proximity to the inside surface of said inner shell and the outlet portion of which extends through the closed'top cfthe chimney, and. a, burner dc tachably securedt; shelzifg f in presence or tuo'witnesses. v lWitnesses:
